The Cashew Scandal occurred in 1219 in the province of Tepytha. Though not technically a duchy, Tepytha adhered to the custom of experimentalism inherited from their motherland, the Sapphire Duchy. Tepytha was founded in 1073 after an exodus of citizens discontent with the Sapphire Duchy's policy of agnosia.

In 1218, the leadership and underclasses of Tepytha were experiencing a tumultuous schism. Six generations after the original exodus, the working class experienced a shift in perspective regarding their ancestors' rejection of agnosia. Many dissidents abandoned the city in favor of the dense tropical forest in the surrounding region. This left a dearth of fit workers within the city. The economy in tatters, the governor instituted austerity measures and opened negotiations with neighboring duchies for economic relief. In the summer of 1219, General Prostro Kalumnius of the Duchy of Palta arrived for a summit with the governor and several other visiting diplomats.

During his procession, dissidents began to hurl raw cashew apples and cashew nuts at the general. The otherwise harmless display of revolt turned into disaster, as General Calumnius was severely allergic to tree nuts. The unfortunate general, thoroughly coated in deadly fruit, died before reaching the city.

This event sparked brutal conflict between Tepytha and Palta. The conflict lasted 2 years and  came to be known as the Kalumnian War, named so after the deceased general and his sons, Lycosor and Locellor, who distinguished themselves during the Siege of Tepytha.
